Rayleigh scattering wavelength size
WebMIe scattering is also the more appropriate model compared to Rayleigh scattering when the particle size is larger than around 10% of the wavelength of the incident radiation. … WebThis paper discusses Rayleigh’s contributions to scattering theory in eight categories: (1) “tenuous scatterers” (relative physical parameters near unity); (2) series solutions for cylinders and spheres (“partial waves”); (3) “small scatterers” (significant dimensions small compared to wavelength); (4) large apertures (applications of Kirchhoff approximations); …
